Essential Question for Algebra I Given a linear equation or inequality, how can the values that make the equation true be found? Topics: algebra, equations

Whenever you have the same number of unknowns as you do equations it should be possible to find the unkowns. (ssuming none of the equations is a multiple of another). Topics: algebra, simultaneous equations

When two things multiply together to equal zero, one of them must be zero. This is the basis for solving quadratic equations. Topics: algebra, quadratic equations

The technique of completing the square can be used when the equation cannot be factorised. As the steps are the same each time, this pattern lends itself to a formula, the formula known as "the quadratic formula" Topics: algebra, quadratic equations, completing the square
